The demand for water is increasing worldwide: in agriculture, private households and industry, the demand for water will continue to rise in the future.

Water infrastructures are constantly growing

Investment in the supply and disposal of water is increasing. In 2025, spending worldwide will exceed US$1,000 billion.

We create direct connections to supply life above ground

Efficient supply and disposal systems are the indispensable arteries of modern cities. With Herrenknecht tunnelling technology, they grow beneath the surface almost unnoticed.

Tunnel infrastructures run invisibly underground but are essential for social, economic and industrial life on the surface. So together with our customers we work to build tunnel structures for water, sewage, electricity and communication on all continents – trenchlessly and with minimal impact on nature and the environment. Every year in small communities, mid-sized towns and major cities or remote industrial regions, many kilometers of new supply and disposal lines are built using our tunnelling technology. Herrenknecht machines can cope with tight space constraints, can be used in all geologies and build high quality tunnel structures with maximum safety. Exactly where they are needed.

Vertical Shaft Sinking Machine (VSM)

The VSM is sinking a target shaft – safely, quickly, and precisely. Thanks to its modular structure, the machine technology can also be used for inner-city projects with space constraints.

The remote-controlled AVN Machine is drilling a tunnel for a new sewage pipeline beneath existing buildings. An AVND Machine provides controlled face support pressure and can be used if overburden is shallow or diameters large.

An EPB Shield is being used to extend the sewage system in soft ground with low permeability. The excavated soil supports the tunnel face. Tunnel lining takes place immediately using watertight precast concrete segments.

AVN machine (pipe jacking)

The remote-controlled AVN Machine installs protection pipes for drinking water pipelines using trenchless methods, providing drinking water directly to the population. AVN technology can be used in all geologies, with small overburdens and under groundwater.

The AVN Microtunnelling Machine connected on top of the pipeline excavates the soil and installs the seawater intake pipeline in one single work step. Subsequently, the machine is recovered from the sea.
